To all Iwlw/m, t may con/:ern

lie it known that I. Join.' M. PALMER, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois. have invented a certain new and useful Improvement in Valves, of which the following is a full, clear. concise, and exact description, reference being had to the ac companying drawings, forming a part of this specification.

My invention relates to valves for use in the control of the fiow of steam or water, and is of particular utility in connection with high pressure work7 inasmuch as the pressure exerted upon the valve is employed to tightly seat the valve member against the coperating casing of the valve when the valve is in its closed position.

M invention is of such a sim )lified constructlon that no packing 1s necessary.

The slmplified construction of my valve facilitates the removal of the same and further reduces the liability for repair.

My invention will be readily understood by referring to the accompanying drawings in which- Figure 1 is a cross-sectional view of a -valve embodying the features of my invention and shows the valve mechanism in its assembled condition. the valve mechanism being shown in this view in its open position. Fig. 2 is an elevational view of the valve member. Fig. 3A is a fragmentary view of the valve member illustrating a ring of Babbitt metal inserted into the valve member. Fig. 4 is an end view of the valve member. Fig. 5 is a cross-sectional view taken on line 5-5 of Fig. 2. Fig. 6 is a modified arrangement of a valve member. Fig. 7 is a central cross-sectional view of a form of valve wherein a modified construction of the valve member is employed.

Fig. 13 is a view taken along lines 13e-13 of Fig. '12. Fig. 14 is a front view of a faucet. Fig. 15 is a vertical sectional view taken on lilies 15-15 of Fig. 14. This figure showsmy improved valve member used in connection with a faucet. Fig. 16 is a View showing a modified form of the valve member in connection with a different form of faucet. Fig. 17 is a top View of the valve member shown in Fig. 15. Fig. 18 is a central sectional view of a valve wherein the valve member has a plurality of seats engaging seats in the casing, this valve member being held in place by a plug at the bottom of the casing. Fig. 19 is an elevational View of the valve member.

As shown in Figs. l to 6 inclusive, the valve consists of a casing 17. in which there is an inlet opening 18. and an outlet opening 19. These openings are threaded at the outer ends to receive pipe connections with which the valve is designed to operate. The valve member 20. is arranged to fit into a bore 21. in the casing. this bore being on an incline with respect to the pipes with which the valve is connected. The valve member 20. consists of a disk 22. at its upper end, and a tubular portion'23, at its lower end, separated by a disk 24. which is not connected to either the disk 22 or the tubular portion 23. of the valve member. The portions 22 and 23, are connected together by a web 25. as shown in Fig. 5. This web is enlarged at 26, and extends a short distance inwardly beyond the disk 24, as shown in Fig. 1. The valve member 20. is preferably formed of cast metal. as castiron or cast brass. and during the casting operation, the disk 24. is inserted in place. said disk consisting preferably of steel having smooth upper' and lower surfaces` as a result of which the disk 22 and the tubular portion 23. fit closely to the upper and lower surfaces of this disk. The smooth steel disk it will be understoml. has a slot extending into it from one edge. as indicated in Fig.

so as to receive the web 25 and the enlarged portion 26. thus connecting the portions 22 and 23. This smooth disk 24. serves to permit expansion and contraction of the tubular portion of the valve member relatively to the portion 22 of this valve member. and at the same time fills the space between the tubular portion and the portion 22. so that leakage will be practically prevented from the lower portion of the valve 'maintaining a verv close fit therewith.

casing past the disk 24. into the upper p0rtion of the valve casing. The smooth surfaces of the disk 24, permit the tubular portion to move freelv relatively to said disk when the tubular portion is expanded or contracted. and these smooth surfaces further Serve to aord a tight joint between the portions 22, and and the disk 24, as a result of the casting ope ation. During this casting operation, the surfaces of the disk 24 are not changed by the hot metal, inasmuch as a chilling action ensues imn niediatelv upon the melted metal striking the disk 24. Thus the smooth surfaces are left practically una'ected. This would occur whether the valve member be cast of brass or cast iron. In constructing the valve member 20, after it is cast with the valve 24 in place, as described, the tubular p01'- tion 23. is slotted. as indicated at 27. As shown in Figs. 1 and 2. the valve member' is provided with openings 2S and 29 on opposite sides of the valve member. The opening 28 has a web 30, extending across from one wall to the other and when the valve member is slotted. the cut is made through this web as shown in Figs. 2 and 4. After the valve member is slotted, the tubular portion is then drawn together by a bolt 31, and a suitable nut engaging therewith. The outer surface of the valve member 20, is then turned and ground to the exact size of the finished cylindrical bore 21, after which the web 30. is cut away. so as to complete the opening 28. lVhen the valve member is inserted into the bore 21, it will spring outward and completely fill the bore, trims ie disk 22, of the valve member. is provided with a` Stem portion 32. which terminates in a squared portion 33. which is engaged by a suitable hand-wheel 34. held in place by means ot' a washer 35, which washer is engaged bv a bolt 36, threading into the squared portion -A split washer 37. is interposed between the casing 17 and the hand-wheel 34. It is to be here noted that the disk 22. has a conical seating surface 38, which is adapted to engage the seat 39, in the valve casing. The valve casing is provided with an oil chamber 40, which may be filled with oil bv means of the opening 41, extending through the casing. Thel lower portion of the valve member 20, is

beveled as shown, and is adapted to coperate. with a threaded plug 42, which has a beveled seat 43. pressing against the beveled portion on the valve member, this plug having a squared opening 44. so that it mav be forced into place. This plug serves primarily to force the valve member against the seat 39, so that there will be no possibilitv of leakage between this seat and the seating surface 38. on the valve member. The valve as shown in Fig. 1, is in its open position and permits free communication between the inlet opening 18, and the outlet opening 19. Whe-n the valve is closed, the position of the valve member willA be reversed, thus bringing the openings 28 and 29 against the walls of the casing 17. when communication between the inlet and Outlet opening will be closed.

The valve member 20, as shown in Figs. 1 and 3, is provided with a' ring 45, of Babbitt metal, which forms a non-corrosive Seat around the outlet opening 19, `when the valve is closed. By providing such an arrangement. the valve member is prevented from deteriorating after it has been closed for any great length ott time, and then suddenly opened, inasmuch as the Babbitt metal forms a seat around the opening such that corrosion is prevented. WVhen the valve member is in a closed position, the slot 27, registers with the inlet opening 18. Consequently the valve member will spread outward owing to the lpressure of the water or steam, and thus the valve member will fit tightly in the bore 21. As shown in Fig. 4, the tubular portion 23, is constructed so that the slot 27 is at the na'rrowest or thinnest portion thereof. In other Words, the walls of the tubular portions 23 gradually increase in thickness as they near the web T his arrangement permits the walls to spread out more readily at those portions nearest the slot 27.

Referring now to Fig. 6, it will be seen that the slot 2T", is disposed at right angles with respect to the web 25, instead of being diametrically opposed. as shown in Fig. This construction it will be noted, provides a. comlniratively long wall 46, which is adapted to spread out quite considerably in the bore 21. In other words. when the valve member is in a closed position, the wall 46 serves to engage the bore very snugly and thus prevents any leakage between the engaging surfaces. This particular arrangement increases the engagement of the valve member against the outlet opening 19, inasmuch as the web portion 25a, is not disposed over the opening, in the casing, but. is located between the openings when the valve is closed.

l have found it preferable to construct theI valve member 20, of cast iron, and the casing 17 of cast brass, inasmuch as these metals wear upon each other better than a cast brass valve member would upon a cast brass casing. and moreover cast iron is more elastic than cast brass. thus affording a bot ter fit between the valve member and the casing than it' the valve member were made of cast brass.

As shown in Fig. 7, the valve member is composed of two parts, a tubular portion 47, having a web 48 extending therefrom, and which is secured to the disk 49, by means of a pin 50, the tubular portion 47 being provided with a slot 51. and an opening 52, adapted to register with an outlet opening 53, in the valve casing 51. The disk 19, has an extension 55, which is engaged by a handle 56. and held in place by means of a pin 57. engaging in a slot in the extension 55, and a similar slot in the handle, so as to prevent relative movement thereof. A washer 58 engages the handle and coperates with a bolt 59, which threads into the eX- tension a split washer 60, being interposed between the handle and the valve casing 5-1. The bolt 59 when secured tightly into the extension 55, serves to draw the disk 19. so that the conical surface 61, will firmly engage with the seat G2. on the casing. An oil chamber (S3. is arranged so as to be filled through an opening extending through the easing. The alve member as shown in the drawing` is in its open position` so as to permit connnunication between the inlet opening o4. and the outlet opening 58. When it is desired to close the valve it is rotated so as to bring the opening out of registration with the outlet opening for which position the pressure of the water or steam will force or spread the tubular member 17, so that it will firmly engage with the bore of the valve, thus preventing any leakage between the engaging surfaces.

Referring now to Fig. 8, the valve member 95 is constructed so as to have a tubular portion G6, and a disk portion 6T, between which is interposed a steel disk 68, which is of the same conformation, and which is held in the valve member in the same wav as described in connection with Fig. 1. The disk portion 6T has an engaging seat 69. which engages with a cap 70. having a seat'71. This cap is screw threaded into the valve casing T2. and has a portion thereof extending into the bore 73, so that the seat 71 is properly centered for engagement with the engaging seat 69 on the disk (S7. The disk (37 has an extension 74, which is squared at 75 for engagement with the handle 7G, a split washer 7T being interposed between the handle and the cap 70. A washer 78, and a threaded bolt 79. passing through the washer and into the extension 74. are employed to maintain a firm engagement of the disk (i7 with the seat 71. A suitable oil chamber 80, is employed for supplying oil to the engaging surfaces, this chamber having connection with an opening through the cap 70. so that it may be filled with the 'proper amount of oil.

The valve member as shown in the drawing, is in its open position, that is to say, the opening 81 communicates with the outlet opening 82. When it is desired to close the valve, the handle is turned so as to bring the opening 81. out of register with the outlet opening, for which position the pressure of the steam or water will spread the tubular portion 66, so as to bring it into firm engagement with the valve casing. This form of valve permits the valve member to be easily removed, and this is effected by first removing the handle, after which the cap 70 may be unscrewed. This cap it may.

be stated, has a hexagonal head, which may be engaged by suitable tools, so that it may readily be removed whenthe valve member can be withdrawn.

Referring now to Fig. 9 there is shown a valve casing 83, provided with an inlet opening 84, and an outlet opening 85, which are arranged to make suitable connection with a valve member 86. This 'alve member is cast so as to have an opening 87, passing therethrough, and it is provided with beveled portions 88 and 89, which engage with seats 90, and 91 respectively. 'lhe lower portion of this valve, it will be noted, is of slightly larger diameter than the upper p0rtion, and this lower portion is provided with a non-corrosive bearing 92, which may be of Babbitt metal. A plug 93, is screw threaded into the valve casing 83, and has a squared opening 91, adapted for engagement with a suitable tool, so that it may be forced into place and against the valve member 86, as shown in the drawing. When this plug is firmly secured into place, the engaging surfaces 88 and 89 are firmly seated against the seats 90 and 91. This valve member has an extension 95, which may be squared at 96, so that it may be engaged by suitable hand wheel or for that matter, any tool so that when it is desired to close the 'alve, the valve member can be turned so as to bring the opening 87 out of register with the inlet and the outlet openings. The valve casing 83, is provided With an oil chamber 97, which has suitable communication with the outside of the casing, so as to permit the ready introduction of oil.

Referring now to Fig. 10, there is shown a valve member which is of the same Construction as shown in Fig. 8 except that the extension 98, is threaded and engages with a nut 99, and a lock nut 100. This arrapgement-maintains the valve member in firm engagement with the seat 101, independent of any mechanism used in connection with the handle. In fact 'in this form of valve, a handle may be used or the valve may be opened and closed by applying a suitable tool to the squared portion 102, of the extension, which extension forms a part of the cylindrical disk 103, and between which and the tubular portion 104, there is interposed a disk 105, which is secured in place in the same manner as described in connection With Figs.' 1 and 8. Suitable oiling means are employed to keep the engaging surfaces properly lubricated.

Referring now to Fig. 11, there is shown a modified arrangement of the upper portion of a valve casing, and which is used particularly where it is desired to throttle the valve. The valve casing 106, is screw threaded at 107, and has inwardly engaging portions 108. A cap 109, engages with the threads and also engages around the shank 110, of the valve member 111, this cap being provided with a cylindrical member 112, engaging in a pocket 113, formed at the upper portion of the valve casing. A split metal friction ring is disposed in this pocket, and when the cap is screwed down into place, the member 112, serves to force the ring into tight engagement with the shank 110. This mechanism provides suitable frictioning means, so that when the valve is used in connection with high pressure work, this valve may be set in any position desired and it will remain in such position owing to the frictioning means employed. This arrangement then insures the proper throttling of the valve.

Referring now to Figs. 12 and 13, there is shown a. straight way valve which has a casing 114, arranged with an inlet opening 115, and an outlet opening 116 to be connected with suitable piping. The valve member 117, is adapted to be raised and lowered in order to open and close the valve. The casing is provided with a downwardly extending portion 118, into which the valve member engages when the valve is closed, and there is also an upwardly extending portion 119, for engagement by the valve member. vide a vertical bore 120 for the valve member 117, and which is closed at the top by means Aof a cap 121, screw threaded around the portion 119. The valve member 117, has a web 122, provided with an enlargement 123, which has an opening 124, which opening is engaged by the squared portion 125, of the stem'126, this stem being connected at its upper portion to a bar 127, pivoted at 128 to a link 129, which is pivoted at 130 to the valve casing. T he squared portion 125 maintains the Valve member in a certain-relative position with respect to the casing. That is to say, it is prevented from turning when it is raised and lowered by means of the handle or bar 127. The valve member 117, consists of a disk 131, and a tubular portion 132, and a lower cylindrical portion 133, this lower portion being provided with a transverse opening 134` which is adapted to register with the openings 115 and 116, when the valve member is raised, thus providing a straight passage for the steam or water. The valve member 117, is preferably formed of cast metal such as cast iron or cast brass, and during the casting operation, the disk 131, is inserted in place, said disk consisting preferably of steel having smooth upper The portions 118 and 119 pro` and lower surfaces as a result of which the tubular portion 132, and the cylindrical portion 133, fit closely to the upper and lower surfaces of said disk 131. The disk 131, is smooth on its upper and lower faces, and has a slot extending into it from one edge, as shown in Fig. 13, to receive the web 122, connecting the portions 132 and 133. This smooth disk serves to permit expansion and contraction of the tubular portion 132 of the valve member, relatively to the portion 133, and at the same time fills the space between the tubular portion and the portion 133, so that leakage will be practically prevented when the valve is closed. The smooth surfaces of the disk 131, permit the tubular portion to move freely relatively to Sayid disk, when the tubular portion is expanded or contracted, and these smooth surfaces further serve to a lford a tight joint between the portions 132 and 133, and the disk 131, as a result of the casting operation. During the casting operation, the surfaces of the disk 131 are not changed by the hot metal inasmuch as a chilling action takes place immediately upon the melted metal striking the disk 131, and the smooth surfaces are left practically unaffected. In constructing the valve member 117, after it is cast with the disk 131, in place as described above, the tubular portion 132, is

slotted as indicated at 135, and such tubularportion is then drawn together by a screw 135', which is adapted to engage with the lugs 136. The outer surface of the valve member 117, is then turned and ground to the exact size of the finished cylindrical opening 120, after which the screw is cut so that the tubular portion 132, may spring outward. As shown in Fig. 13, the walls of the tubular portion are quite thin near the slot 13.5, and gradually increase in thickness away from this slot. This particular construction permits the tubular portion to expand more readily near the slot 135, and thus fit snugly into the opening 120. In. addition to the tendency of the metal to spring outward, the pressure of the steam or water serves to increase the pressure of the tubular portion against the bore or opening 1.20. so that a very tight engagement of the surfaces is secured.

The cap 121, is provided with packing 37, around the stein 126, which packing is held in place b v a gland 138, which is forced into position by suitable means, such as bolts. \Vhen the valve member 117, is in its lower or closed position, as shown in the drawing, steam or water will collect in the upper portion of the opening 120, and in order to raise the valve member provision must be made so as to permit the uid to flow beyond the valve member, and to this end there is provided an opening 139, passing through the disk 131, and through the upper portion of the cylindrical portion 133. The liquid flows through this opening when the valve is raised, and into the transverse passageway 131. After the valve member has been raised, and it is desirable to lower the stem, it is necessary that provision be made for the escape of the liquid which has collected in the bore in the lower portion 118, of the valve. To this end there is provided an opening 140, in the cylindrical portion 133, so that as the valve member is forced downward, the liquid passes through this opening, and into the passageway 134, and may also pass through the opening 139. This arrangement prevents any impediment to the proper operation of the valve member.

Referring now to Figs. 11 and 15, we have an arrangement by which a valve member is arranged in connection with a faucet so as to open and close the same. The wall faucet 111, is provided with a vertical cylindrical bore 112, in which the valve member 113, is adapted to be reciprocated by means of a handle 144, this handle being secured to a squared portion of a spindle 145, which is journaled in bearings 146. The valve member 143, has a web 147, which has an opening 118, and which is flared at 149, this opening being engaged by a rod 150, which is secured to the spindle 145. This rod 150, passes through a slot 151, in the faucet. The valve member is constructed so as to have a tubular portion 152, and a cylindrical lower portion 153, a steel disk 154, being cast between these two portions. This disk is provided with smooth surfaces, so that when the casting operation is being performed, the metal will not adhere to the smooth surfaces, since it is chilled, and thus prevented from becoming attached to this disk. After the valve member is cast, a slot 155, is cut into the tubular portion 152, so as to permit this portion to spring outward. After the tubular portion has been slotted, the walls of this portion are drawn together by mea-ns of a screw, which is adapted to engage the lugs 156, after which the valve member is turned and finished to the proper size. It is then inserted into the bore 142, in the faucet, after which the screw may be cut so as to permit the walls of the tubular portion 152, to spring out and tightly and snugly engage the bore. The bore 142 is closed b v means of a cap 157, after the valve member has been put in place. The cylindrical portion 153, of the valve member has a transverse opening 158, which is adapted to register with the inlet opening 159, when the valve member is raised, so as to permit the flow of the liquid. The valve member 143, is provided with openings 160 and 161, which offer a path for the fluid when the valve member is lowered into its closed position, the passageway 161, also providing a path for the liquid which has naturally collected in the upper part of the bore 142. That is to say,

`a part of this liquid will flow through this opening, as the valve member is being raised to its uppermost position.

Fig. 16 shows a faucet 162, which has an inlet opening 163, and an outlet opening 164. The valve member 165, is provided with a web 166, having an opening 167,v flared at 168, this opening being engaged by a rod 169, secured to a spindle 170, which has a handle 171, attached thereto, this spindle 170, being ournaled in suitable bearings 172, on the faucet. The casing of the valve has a slot 173, through which the rod 169 extends, this slot being of such conformation that the valve member 165, may be raised and lowered by means of the handle 171. The valve member 165, is adapted to reciprocate in a vertical bore 174, in the casing of the faucet, this bore being closed at the top by means of a cap 175. The valve member 165, has an upper cylindrical portion or disk 176, and a lower tubular portion 177, a steel disk 178, being interposed between these two portions. The valve member 165, is preferably formed of cast metal, such as cast iron, and during the casting operation the disk 178, is inserted in place, said disk consisting of steel, having smooth upper and lower surfaces, as a result of which the disk 176, and the tubular portion 177, lit closely vto the upper and lower surfaces of said disk. After the casting operation, the tubular member is slotted at 179, and then this portion is drawnv together and turned and finished so that it will fit in the bore 174. Suitable lugs 180, a re provided on each side of the slot, so as to be engaged by a suitable screw for holding the parts together after the slot has been made. After the valve member is in place, the screw is severed or cut, so that the tubular portion 177, will spring outward and tightly engage with the bore 174, so that when the valve member is in its closed position, there will be no leakage from the inlet opening to the outlet opening of the faucet. The valve member has an opening 181, which passes through the disk 176, and the steel disk 178. This opening provides a. path for the liquids which may have collected in the upper portion of the bore 174, so that as the valve member is raised, the liquid may flow through this opening, thereby no impediment will interfere with the proper operation of the valve member.

Referring now to Figs. 18 and 19, there is shown a valve for the control of liquid or water and which has an outer casing 190 and a valve member 191 which is composed of two parts, the lower part 192 and the upper part 193. The lower portion is cored out so as to form an opening 194, which leads from the bottom and through one side of the valve member, as shown in vthe drawings.

The lower portion 192 has a web 195 which extends upwardly and is secured in the upper portion 195i by means of a pin 190 which passes through the shank 197, this shank being squared at 198 and being engaged by a suitable handle 199, which is held in place by means of a washer 200 and a bolt 201 which threads into the shank. A split washer 202 is interposed between the handle and the casing. The casing is provided with an oil chamber 203 which communicates with a suitable opening 204; so that it may be filled with lubricating oil. The valve member 191 is provided in its upper portion with a beveled seating surface 205, which engages a similar surface 206 in the casing. At an intermediate point the valve member is provided with a seating surface 207 which engages a similar surface 208 in the casing, this seating surface being disposed below the outlet opening 209 in the valve casing. In order to keep the valve member in place inthe casing, I have arranged a plug 212 which has threads 213 engaging similar threads in the end of the casing. This plug has a flange 214, the outer surface of which may be of hexagonal or octagonal shape, in order that a proper tool may be applied so that it can be screwed into place against the valve member. It is desirable to have a split spring or washer 215 interposed between the plug and the end of the valve member. lVhen the plug is screwed tightly into place, the various seating surfaces engage the seats in the casing so that leakage is absolutelyv prevented because of the irm engagement of the cooperating surfaces. This type of valve can be used for a variety of purposes, in fact, in any instance wherein a rightangled valve can be employed. The outlet opening 209 is screw-threaded, as shown, so that it may be connected with suitable piping. The plug 212 has an opening 216, which is also screw-threaded and which is designed for connection with suitable piping. The valve member 191 is provided with seats of Babbitt metal, which provide bearing surfaces that do not wear very easily and which are nml-corrosive. As shown in the drawings, the up er portion 193 has a dove-tailed groove 2l); in which is disposed Babbitt metal 218 which forms a bearing seat against the bore 219. At an intermeH 4Kliate point, the valve member is provided with a dove-tailed groove 220 which is arranged to receive Babbitt metal 221 which also engages the bore 219. At the lower portion of the valve member a dove-tailed groove 222 is provided which receives a Babbitt metal bearing 223 which is adapted to form a bearing surface against the large bore 224, there beiner suitable clearance between this bore and:` the valve member, as shown. The casing has an intermediate bore 225 with which the enlarged portion 226 of the valve member engages. By providing the valve member with a plurality of seating surfaces and a plurality of Babbitt metal bearings disposed at suitable intervals along the length of the valve member, a very satisfactory result is secured, in that the engagement of the valve member and the casing is at all times firm and secure and there is never any liability of the valve member becoming loosel in the valve casing because the valve member is made preferably of cast iron and the casing may be made of cast brass, or vice versa.. The Babbitt metal bearing seats are particularly useful where the valve has not been used for any great length of time, and upon being put into use or turned the bearing surfaces are not destroyed but are kept intact so as to prevent any leakage. Then it is desired to close the valve all that is necessary is to manipulate the handle 199, so that the opening 1911 is brought out of registration with the outlet opening 209, thus closing communication between the inlet opening 216 and the outlet opening 209.

lVhat I claim is:

1. In a valve, the combination of a casing having inlet and outlet openings at opposite ends thereof, a valve member comprising a metal cylinder hollow at the upper end and capable of expansion, a metal disk separating the hollow portion from the body of the valve member, said valve member having a transverse portfor communication with the inlet and outlet openings in the casing when said .valve member is in its raised position, and devices for raising and lowering said valve member.

2. In a valve, the combination of a casing having inlet and outlet openings at opposite ends thereof, a valve member comprising a metal cylinder hollow at the upper end and capable of expansion, a metal disk separating the hollow portion from the body of the valve member, said valve member having a transverse port for communication with the inlet and outlet openings in the casing when said valve member is in its raised position, devices for raising and low- @ring said valve member, and means to revent the turning of the valve member W en it is raised and lowered.

2l. In a valve, the combination of a casing having inlet and outlet openings at opposite ends thereof, a valve member comprising a metal cylinder hollow at one end and capable of expansion, a metal disk separating the hollow portion from the body of the valve member, said valve member having a transverse opening extending through the lower portion thereof and adapted to register with the inlet and outlet openings when said valve member is in its raised position, a spindle extending from said valve mem ber and a handh` tor raisinfr and lowerin f said valve member.

l. In a valve, the combinationfoi a easing having inlet and outlet openings at opposite ends thereof, a valve member cornprising a metal cylinder hollow at one end and capable of expansion, a metal disk separating the hollow portion from the body of the valve member, said valve member having a transverse opening extending through the lower portion thereof and adapted to register with the inlet and outlet openings when said valve member is in its raised position. a spindle extending from said valve member, and a handle for raising and lowering said valve member, the lower portion of said spindle having a squared portion for engagement with said valve member thereby7 preventing the turning of said valve member when it is raised and lowered.

In a valve, the combination of a easing having inlet and outlet openings, a valve member comprising a metal cylinder hollow at one end and capable of expansion, a metal disk separating the hollow portion from the body of the valve member. a web extending from said valve member, said web having an opening flared at one end, a rod extending into said opening, means for engaging said rod to raise and lower said valve member, the lower portion of said valve member having a port extending therethrough which when the valve member is in kits raised position registers with the inlet and outlet openings.

6. In a valve, the combination of a casing having inlet and outlet openings, a valve member comprising a metal cylinder hollow at one end and communicating with the inlet opening, said hollow portion of said valve member being capable of expansion to fit tightly in the bore of said casing. a metal disk separating the hollow portion from the body of thel valve member. a web extending from said valve member, said'web having a flared opening, a rod extending through said casing and into said opening. deviees'for engaging said rod so that said valve member may be raised when desired to open the valve, said valve member having an opening extending through the disk and the upper portion thereof so as to prevent the formation of an air cushion when the valve member is raised.

7. A valve comprising a casing, a bore in said casing, inlet and outlet openings oommunicating with said bore, and a valve member movable lengthwise of said bore to control communication between said inlet bore to control communication between the inlet and outlet openings, said valve member comprising a solid portion, a split tubular portion partially separated from saidv solid portion, a metal packing member between the solid portion and the split tubular portion, and a portion having a transverse bore therethrough carried with the first-mentioned portions of the valve.

9. A valve member comprising a hollow casing, inlet and outlet openings in the casing, and a valve member comprising a split tubular portion, a second portion carried with the said split tubular portion but partially separated therefrom, said second portion having a transverse bore therethrough adapted to be brought into register with the inlet and outlet openings, and a metal packing member between the aforesaid portions of the valve member.

10. A valve comprising a hollow casing, inlet and outlet openings communicating with the casing, and a valve member movable within the casing, said valve member comprising a split tubular portion, a second portion partially separated from the split tubular portion and movable therewith, a metal packing member between said portions, said second portion having a transverse bore therethrough adapted to be brought into register with the inlet and outlet openings.

11. A valve comprising a` casing, a bore in said casing, inlet and outlet openings `communicating with said bore, and a valve member operating in said bore to control communication between said inlet and outlet openings, said valve member comprising a solid portion, a split tubular portion partially separated from said solid portion, and a metal packing member between the solid portion and the tubular portion.
